IMPROVEMENT IN IBINDING-GUIDES ron SEWING-MACHINES.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern:

Be it known that I, WALTER S. Hororrnrss, of Bridgeport, in the countyof Fairficld, and State of Connecticut, have invented a new Improvementin Binding-Guide for Sewing-Machine; and I do hereby declare thefollowing, when taken in connection with the accompanying drawings, andthe letters of reference marked thereon, to be a full, clear, andexactde- Figure 1, atop view;

Figure 2, a side view; and in V Figures 3 and 4, side views, the partsbeing difiercntly adjusted.

This invention relates to an improvement in apparatus for attachment tosewing-machines, for the'purpose of turning the binding over the edge ofwork, commonly called a binding-gauge; and

The invention consists in the upper and under. gauge or folder, fixed toa plate, in the manner hereinafter described, so that both the upper andunder gauges are made adjustable together, as well as the oue'inde- Toenable others to fully understand my invention, I will proceed todescribe the same as illustrated in the accompanying drawings.

A is the plate or base by which the gauge is attached to the work-table,its inner end forked, so as to form a guide, a a, for the edge of thework.

Upon the under side of the said base is fixeu a gauge, (1, secured tothe plate by a nut, f, on the bolt t, which extends through the plate.

Upon the upper side of the plate A, another gauge, 1), is attached,lying between the forks a, in the end of the plate A, and is secured tothe said plate by a screw, B, and is slotted, so as to pass over thebolt't', and pressed down, or adjusted vertically, by a nut, a.

As seen in fig. 2, the two gauges are drawn back close to the folder orfork to The work is placed between the two folders, and the two edges ofthe binding, one into each bend thereof, and is thus guided to theneedle. 1

If itis desirable to adjust the lower gauge independently of the upper,say as from the position in fig. 2 to that in fig. 3, loosen the twonuts f and n, (the 'screw B holding the upper guide firmly,) then theldwer guide may, be moved 'out to thc position' seen in fig. 3; thelower nut f turned, to fix the lower gauge; then the upper gaugeadjusted as to the thickness of material, by turning the nut 02 down,until the proper scription of the same, and which said drawings consti-,tute part of this specification, and represent, iiirelative positionbetween the two is attained. Or, if

" desired to adjust the upper gauge independently ofthe loweryloosen thescrew B, and move the upper gauge to the desired position; then set thescrew B, to fix the gauge in that position.

By this construction, it will be observed that the two guides may be settogether, that is, in proper relative position to each other; then bothadjusted, without disturbing their relative positions, and this in thefollowing manner:

Supposing the position in fig. 1 to be the proper relative position toeach other, and that it is desired' to retain that relative position,but in a position further back, turn the nut f, so as to clamp the upperguide between the adj ustiiigenut n and the said nut f; then the twoguides are both clamped firmly together; then,'by loosening theadjusting-screw B, the two guides may be moved together.

I do not'wish to be understood as broadly claiming the arrangement oftwo folders or guides, .for guiding and folding the binding over amaterial in sewing-Inachines, as such, I am aware, is very common; but

What I do claim, and desire to secure by Letters Patent, is

\ The combination of the plate A with the upper and lower guides l) andd, with their respective nuts or screws, f and B, and adjusting-nut a,arranged and operating together as and for the purpose specified.
